PEQ-15 mounting question

[Gnzrme]

So I only have about 4 or 5 slots of picatinney mounts behind my A2 FSP. Is that going to be enough to mount a PEQ-15? Do I need to remove the FSP?

Been awhile since i ran a peq15. Should be fine. If it doesnt fit run it at 9 or 3 with a 12:00 pad, or grind off the fsp (not the gas block) and run a LEAF

Mine works fine with my front sight up. It should be fine.

Just don’t over tighten it and crack the housing.
